The formula for the nth term is a(n) = a(1) + 2(n - 1)
First term: n = 1. Then a(1) = 3 + 2(0) = 3 (as expected).
5th term: n = 5. Then a(5) = 3 + 2(5 - 1) = 3 + 8 = 11
...
and so on.
Answer: 19
Step-by-step explanation:

Answer:
9 hours
Step-by-step explanation:
If she makes $ 20 for each car, washing 9 cars in 3 hours would get $ 180.

In summary she must work 9 hours
